I was reviewing our projects for the next year and we are contemplating an Exchange upgrade to Exchange 2007. We are not a big shop. We have three existing geographically-dispersed Exchange 2003 servers servicing about 500 accounts. I went through and worked up the costs for licensing (servers and CALs), servers (can’t upgrade-in-place to 2007), migration and training (users and admins). Honestly, the cost of doing this is difficult to justify.
So, I started taking a look at alternatives. Google can give me Google Apps Premier Edition for $50 per user per year. With this we get 25GB of mail storage per account, redundant servers, a 99.9% uptime SLA plus other apps such as Calendar, IM, etc.
Anyone using
Premier Edition? If so, please share your experiences. I'm not close to a decision, but I want to weigh the alternatives.
